Application filed March 18, 1911, Serial no. 615,198.:

To all whom it may concern: v

Be it known that I, DAVID STRICKLAND, a

citizen of the United States, residing in the city of, New York, borough of Bronx, county and State offNew York, have invented certain new and useful Improvements in Brick making-Machines, of whichthe following is a full, clear, and exact specification;

This invention relates. 'to. brickjmaking and has for its object to provide an im'-:.

proved brick making machine. The object of the invention isparticularlyto provide v improved mechanism for molding bricks comprising a separable mold located at position to be filled withthe mud, media I nlsm for removing the molded brick upon; release from the mold, anddeliveririg the same to a conveyer, andla sander for sanding the mold, While-moist after each .dis

A-mud box designated by the referencecharacter 5 is shown supported on afra'me Work. The frame work carries a driving shaft 6 driven by means of apulley 7 from. some. suitable source ofpower. A shaft 8 for the mixer will be driven by means of a tram of gearlng from..the driving shaft.'

The mixer. is a mereincident and is not illustrated or described, With particularity fThe front end of the machine" isprovided with a mud-spout 9'Which will "be supplied with the mud through a suitable opening .10 in the mud box. The mud of course, will .be moved toward this opening by means of the agitator in a well-knownfmanner. A plunger 11 is mounted in the spout for the purpose of forcing the mud outfofthe spout. This plunger; is c'onnectedby; means of apitman 12'to a crank113c'arr1ed byia shaft 'lhiwhich h t is driven, by means of a 'pulley' 5 0 and belt 51 from a pulley 52 on shaft 6'.

a rock -lever-l7 which is mountedon-a rockshaftls. y

- In the present illustration the mold is opentop and bottom and is fixedly supported at the discharge opening of the spout.

Themold herein illustrated is a separable or-openable mold which will beclosed for receiving the mud and which will beo'pened at the proper time for releasing the molded brick. The mold is shown comprising two side members 20, 21, one of which,-as for instance the most backwardly disposed mem- Mea an 91a;

ber 20 may be fast to its supports 22 and the other may be movable therein towardand from the other upon a horizontal plane.

A lever 23 ,isshown pivoted on thestationa arysidejmemberQO and connected by means. of a1link24 with the movable member 211 and'by means, of a link 25 with a rock arm 26 fast on ther0c'k shaft 18. This lever mechanism for actuating the mold is duplicated on the respective sides oftthemachine for the purpose of moving the parts in unisongand. for holding them locked. in

the closed position duringthe pressure upon.

the mud.

The divisions .for forming the individual;

bricks will bein the present illustration-pro duced by means of a series of partitions 27, The ends of the partitionsenter mortises; 28

inthe members 20, 21. In the present illus} tration there are seven partition'sgthe. moldbeingconstructed for molding SIX brick at any operation. The number of brickto be madeateach operation inany particular machine may be varied. by varying;the=number of partitions and associated parts .jThe ends of the partitions are shown carried by guides in the nature of pins 29 extending through suitably formed openings in the side members '20, The respective ends of the partltlons are shown chamfered at-30 for perm tting aisldewise movement of the partitions longitudinally of the side members, when thedevice is opened and also for the purpose of. more readily assistlng 1nguiding the parts to their desired positions after therehas been 1nd1v1dual movement of these-members relative to theside'members.

The mold portion of the device embodies-a ser es ofmold spaces, each having a pair .of-

side walls --a nd apaijr of end walls disposed in position for forming a brick,,having greater, length than width, The sidewalls are separable one from the other by relative movement in, a path perpendicular to their mold faces, and the'end walls are similarly separable by relative movement in a path perpendicular to their moldfaces.

A pallet support 31 is provided whlch will move a pallet 32 against the lower face of themold and them support it during the pressing operation. The pallet support is mounted on a pair of plungers 33 supported by suitable guides 34: and is shown as having a vertical movement. The plungers are fastened to levers 35' which are connected by means ofylinks-SG'to rock arms 3'Zon the 7 rock shaft 18. The pallet support actuating mechanism. is so timed that a pallet will bei presented to the open lower end of the mold and serves as a closure for the vent, which such lower open end is since the molded I brick are there dischargech'and withstands the pressure of the plunger during the; pressing operation. The pallet will p'refen ably be locked: against the action of the mud plunger. "In the present illustration the I rock arm'37 hasa suflicient overthrow for shifting the pivotalxconnection 38 between the arm 37 and link 36 past the straight line between the axis of the rock shaft 18 and the pivotal connection 39 between the lever and link 36. The releasing movement for the pallet support will be the movement of the pivot-38'toward the right in Fig. 1.

The dressing knife 10-is mounted to'move across the top of the mold and be guided,

. thereby. It is connected by means of a pair of. pitmen 4'1 with rock arms lilfast-upon the rock shaft18 and sotimed that after i the mud has been pressed into the mold and the plunger 11 has commenced-to raise and 7 thereby release its pressure upon the mud it will'be moved forward across the face of the mold and dress .and form the top face 7 of the brick, the bottom face of the brick being formed-by the pallet.

After the brick have been molded and dressed the mold will be opened for releasing the brick from the mold and the pallet.

that upon the lowering of the loaded pallet it will be placed upon the conveyer and moved from the machine.

A sand box 44 is mounted on suitable guides 45 which are so located that the sand box may be drawn into position to deliver sand'in the mold. Thesand box is provided with .a suitable agitator, as for instance with an air blast device illustrated in a general way by 46. A pair of pitmen 47 are connected toithe ends respectively of the sand box and are connected to rock 7 arms 48 on the rock shaft 18. The actuator mechanism for the sand box is so timed that the sand boxwill be drawn under the mold as soon as the pallet support has been lowered sufficiently for this purpose. A tripping device designated by 49 is provided for releasing the sand agitator after the 7 sand box has been brought under the mold.

In the present illustration an air cock is provided which will be opened by engaging the tripping device 49. 'The'sand: box will be drawn into position under the mold, the

air cock opened, sand willbe blown upon I the moist surfaces of the Ymold ,the sandbox will be moved away with the incident closing-of the air cock andthe moldswill be againclose'd, a fresh pallet will be placed upon the supportwhich will be moved to the botton'i of-the closed molds; the dressing knife which acts as a valve will be withdrawn from the bottom' of the spout and theplunger again actuated to-press a fresh charge of mud into the molds.

It will beappare'nt that changes of construction may be-made without departing from my invention.
